Description of problem:
I had Fedora 19 with fglrx. I unistalled fglrx and upgraded to Fedora 20 using
fedup. Everything OK.
I then found out that i forgoted to remove from /etc/modprobe.d/blacklist.conf: 
blacklist radeon
blacklist radeonhd

When I removed them and rebooted, I had only black/colour blinking stripes on
my screen (photo in [1]).

I thought that I broke something with the fglrx so I inserted Fedora 20 DVD and
wanted to do clean install. But when the DVD booted there were the stripes
again.

I have ATI Radeon HD 7870 XZ

Version-Release number of selected component (if applicable):
xorg-x11-drv-ati-7.2.0-3.20131101git3b38701.fc20.x86_64
kernel-3.12.7-300.fc20.x86_64

How reproducible:
Every time i remove 'radeon' from blacklist and reboot.


Steps to Reproduce:
1. Remove 'radeon' from blacklist
2. Reboot


Actual results:
There is several seconds of black screen and then black/color blinking stripes
on the screen.


Expected results:
It should start Gnome and run smoothly.
